I've tried Bullseye, Power Pistol, SR 4756, and Silhouette. Out of those 4 Silhouette is my favorite, with SR 4756 coming in second. I love Silhouette for it's easy metering and consistency. SR 4756 doesn't meter quite as well but it's very accurate in my pistols. The only drawback for it is that I have to use a lot to achieve the same velocity and performance as other powders. What say you? What's your favorite?
